To all whom it may concern:

Be it known that I, JOSEPH W. ALPHoNsE Piirnv, a subject of the King of Great Britain, residing at St. Jerome, Brovince of Quebec, Canada, have invented certain new and useful Improvements in Aeroplanes and I do hereby declare that the following is a full, clear, and exact description of the 1nvention, such as will enable others skilled 1n the art to which it appertains to make and use the same.

The present invention relates to new and useful improvements in aeroplanes and more particularly to that of a bi-plane type.

The primary object -of the invention is the provision of a novel stabilizing means whereby the plane will right itself in. case of any side tipping upon improper manipulation of the operator.

Another object of the invention is the provision of means for actuating the rudder and locking the same in adjusted positions.

A further object of the invention is the provision. of means for actuating the rear elevating planes and locking the latter 1n adjusted positions.

Still another object of the invention is the provision for an aeroplane of a land rudder and means for steering the same during its passage over the ground.

A still further object of the invention is the provision of means for moving the opposite side wings relative to each other and locking them in such position.

A still further object of the invention is the provision of a machine of the above specified type which will be comparatively simple and inexpensive to manufacture, reliable and efiicient in. use and readily operated.

With the above and other objects in view, the present invention resides in the novel features of construction, formations, combinations, and arrangements of parts to be hereinafter more fully described, claimed and illustrated in. the accompanying drawings forming a part of the present application, and in which:

Figure 1 is a perspective view of an aeroplane in accordance with the present invention;

Fig. 2 is a top plan view thereof;

Fig. 3 is a side elevation with parts broken away;

Fig. 4 is a perspective view with parts broken. away, illustrating the interior of the meral 10 designates in general an aeroplane.

comprising the main. supporting standards 11 to which are attached the longitudinal curved and vertical bars 12 and 13 which are connected together by the corresponding bars 14 and braced by the guide wires 15.

A propeller 16 is mounted at the forward end of the machine, while a guide rudder 17 and elevating planes 18 are mounted at the rear of the machine.

The bars 12, 13 and 14 are covered by a suitable material such as shown at 19 to provide the fuselage 20 in which is located the pilots compartment 21.

The motor for driving the propeller is not shown in the drawings, as the same forms no part of the invention.

A transverse shaft 22 extends through the machine and is journaled in suitable bearings 23 secured to the sides thereof. This shaft 22 extends through the upper planes 24 disposed upon opposite sides of the machine and which are connected by the rods 25 to the lower planes 26 which are j ournaled as at 27 for tilting movement relative to the body portion of the aeroplane.

The segmental brackets 28 are secured to the inner ends of the upper planes 24 while additional supporting rods 29 extend through the said brackets 28 and are attached to the wings 24 in. order that the said wings 24 will be operated when the brackets 28 are rotated with the shaft 29.

In order to provide for the tilting of the wings 25 and 26, the outer edge of thebracket 28 upon one side of themachine is provided with a groove 30 in which a cable 31 is disposed. This cable 31 passes over a pulley 32 ournaled in a suitable support 33 within the pilots compartment 21. The pulley 32 is provided with a suitable operating crank 34 by means of which the latter can be rotated in opposite directions and the wings 24 tilted either forwardly or rearwardly carrying with them the wings 26.

In order to lock the wings 24 against any undesired movement, the periphery of the pulley 32 is provided with suitable teeth 35 which engage a locking bar 36 slidably mounted in a guide 37 and actuated through the medium of a treadle 38. A spring 39 serves to normally force the locking bar 36 into engagement with the teeth 35 of the pulley 32 holding it against any undesired movement. When it is desired to actuate the same, however, the treadle 38 is clepressed which frees the pulley 32 making it possible to rotate the same through the medium of the crank 34 in either or both directions for the purpose of tilting the planes 24 and 26 in the manner above referred to.

A similar pulley 40 is provided over which a cable 41 passes to actuate the rudder 17 A locking device 42 corresponding to the pulley 32 and its connection is provided for locking the rudder 17 in its various adjusted positions and preventing its displacement.

A land rudder is shown at 43 and is mounted upon a vertical shaft 44 which carries a pulley 45 keyed thereto over which passes an operating cable 46. The ends of this cable are connected to a cross bar 47 which is actuated by a bar 48 to steer the machine in different directions upon its passage over the ground.

The wings 24, as shown in the drawings, are formed of spaced sections of material shown at 49, and the lower section is cut out at 50 to receive a blade 51 which is hinged at 52 and normally held in closed position, shown in Fig. 6. One of these blades 51 is provided for each of the wings 24, and in order to actuate the same, operating rods 53 are journaled in the frame and extend through the wings having arms 54 provided thereon at one end and cranks 55 at their other ends which are connected to operating chains 56. Upon pulling either one of these chains, the blades 51 will be moved to the full line position shown in Fig. 7, which obviously causes resistance of the wind during its passage through the air and rights the machine in case the same is tilting at too great an angle.

In order to prevent the chains 56 from slipping which might cause the displacement of the blades 51, the said chains are engaged by latches 57 which are in the form of fingers insertible through the links of the chain.

The above described operating parts are all located in the pilots compartment 21 within convenient reach of the seat 58 while, if desired, a suitable wind shield shown at 59 may be employed for the convenience of the pilot.

From the foregoing description taken in connection with the accompanying drawings, it will be manifest that an aeroplane is provided which will fulfil all of the necessary requirements of such a device, and it should be understood in this connection, that various minor changes in the specific details of construction can be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is 1. The combination with an aeroplane of wings, brackets carried by said wings, a groove in said brackets, a cable passing over said brackets and engaging the groove, a pulley engaging said cable, means for actuating the pulley and tilting the wings, and means for locking said pulley against movement.

2. An aeroplane comprising a body portion, tilting wings mounted thereon, brackets carried by said wings, a pulley mounted adjacent said brackets, teeth provided upon said pulley, a spring pressed locking bar engaging said teeth, an operating crank for the pulley, and a cable passing over the pulley and brackets.

3. In an aeroplane such as described, the combination of a body portion, wings mounted to tilt thereon, brackets attached to said wings, a pulley mounted in said body portion, one of said brackets having a groove therein, a cable passing over the pulley and through said groove of the bracket, teeth formed upon said pulley, a guide, a locking bar slidable therein for engagement with the teeth of the pulley, a treadle carried by the locking bar, and a spring yieldingly forcing the locking bar into engagement with the teeth of the pulley.

4. In a machine of the character described, a movable member, a cable engaging same, a pulley over which said cable passes, means for rotating said pulley in opposite directions, teeth formed upon said pulley, and a spring locking member engaging the teeth of the pulley, and a treadle actuating said looking member to release the pulley.

5. In an aeroplane such as described, the combination of a body portion, wings operatively connected thereto, stabilizing blades fitted in said wings and hingedly connected thereto to be moved flush with the wings or to be projected therefrom, a shaft, rotatable rods mounted in the shaft, extensions formed upon the rods and engaging the blades for projecting the latter from the Wings upon In Witness whereof I have hereunto set my rotatiofi of said rodsl, cr fimlil arniis formed hand. 11 ont e0 ositeen so tero s chains od nneoted t said crank arms for aotuating JOSEPH ALPHONSE PEPIN' 5 the latter and rotating the rods, and latches Witnesses:
